Influence of fuel injection pressure for diesel-waste cooking oil cofuel in a research engine
Abstract
Abstract Waste cooking oil (WCO) is one of the products obtained from wastes hostels oil and possesses much alternative fuel for the diesel engine. In the present evaluation, the WCO was used as an alternative fuel for the diesel engine. A blend of B20, B40, B60, and B80 is holding 20%, 40%, 60%, and 80% WCO with diesel fuel for the diesel engine. The direct-injection engine enactment in terms of engine performance and emission was evaluated by different fuel injection pressure. The results show that the blend (B20) give a better performance and reduction in exhaust gas emission when compared diesel fuel with fuel injection pressure (FIP) of 900 bar. At the FIP of 900 bar, the thermal efficiency by 0.62%, specific carbon dioxide by 0.8%, ignition delay by 14.6% was found to be lower. Further, the specific fuel consumption, nitric oxide, and smoke increased by 1.2%, 5.4%, and 25%, respectively, when compared with those of the diesel operating condition.
